Subject: ruby des encrypt

I'm trying to using ruby des encrypt ,
in php(some gives me )
  function encrypt($input) {
    $size = mcrypt_get_block_size('des', 'ecb');
      $input = $this->pkcs5_pad($input, $size);

    $key = $this->key;
      $td = mcrypt_module_open('des', '', 'ecb', '');
      $iv = @mcrypt_create_iv (mcrypt_enc_get_iv_size($td),
MCRYPT_RAND);
      @mcrypt_generic_init($td, $key, $iv);
      $data = mcrypt_generic($td, $input);
      mcrypt_generic_deinit($td);
      mcrypt_module_close($td);
      $data = base64_encode($data);
      return $data;
  }
  function pkcs5_pad ($text, $blocksize) {
      $pad = $blocksize - (strlen($text) % $blocksize);
      return $text . str_repeat(chr($pad), $pad);
  }

or in java
    public String encrypt(String input) throws Exception {
    return base64Encode(desEncrypt(input.getBytes()));
  }
  public static String base64Encode(byte[] s) {
    return new Base64Encoder().encode(s);
  }
   public byte[] desDecrypt(byte[] encryptText) throws Exception {

       byte rawKeyData[] = desKey;
       DESKeySpec dks = new DESKeySpec(rawKeyData);

       SecretKeyFactory keyFactory =
SecretKeyFactory.getInstance("DES");
       SecretKey key = keyFactory.generateSecret(dks);

       Cipher cipher = Cipher.getInstance("DES");

       cipher.init(Cipher.DECRYPT_MODE, key);

       byte encryptedData[] = encryptText;
       byte decryptedData[] = cipher.doFinal(encryptedData);
       return decryptedData;
   }


how can i translate this into ruby?
require 'openssl'
require 'Base64'
c = OpenSSL::Cipher::Cipher.new("des")
c.encrypt
c.key = "4dddb3b191a1c2d8ea1sxcv23"
#or c.pkcs5_keyivgen("4dddb3b191a1c2d8ea1sxcv23")
e = c.update("hellcatjack:111111")
e << c.final
puts Base64.encode64(e)

it's not the same as php...
